Product Overview
This chapter provides an overview of the Cisco 6260 Digital Subscriber Line (DSL) Access Multiplexer
(DSLAM) and its related components, collectively known as the Cisco 6260 system. This chapter contains
the following sections:
•Introduction to the Cisco 6260 System, page 1-1
•Cisco 6260 System Overview, page 1-10
•Management Software, page 1-49
1.1 Introduction to the Cisco 6260 System
The Cisco 6260 system is part of the Cisco DSL product family that provides end-to-end service by
carrying voice or data traffic, or both, between a subscriber’s home or office, a telephone central office
(CO), and various networks beyond. The Cisco 6260 system sends and receives subscriber data (often
Internet service) over existing copper telephone lines, concentrating all traffic onto a single high-speed
trunk for transport to the Internet or a corporate intranet. Before traveling over telephone lines to the
DSLAM at the CO, data is modulated by xDSL customer premises equipment (CPE) devices, which are
connected to PCs or routers at the subscriber site.
The Cisco 6260 system may include the following components:
•Cisco 6260 chassis—A carrier class DSLAM.
– xDSL Transmission Unit—central office (xTU-C) line cards and second generation network
interface (NI-2) card(s)
– Input/output module
– Power entry modules (PEMs)
– Fan trays
Figure 1-1 shows the location of the Cisco 6260 chassis components.

•POTS splitters (optional). The POTS splitter is a passive device that supports simultaneous voice
(basic telephone service) and data services.
Note POTS splitters are available from Cisco Ecosystem partners. Please verify the compatibility with
your Cisco representative.
For POTS splitter information, refer to the vendor documentation.
•Management software—Provisions and manages the Cisco 6260 system.
– Cisco IOS—A command-line interface (CLI) that is available for network
element provisioning.
– Cisco DSL Manager (CDM)—An element management system designed to configure and
manage the 6xxx series of Cisco IOS software-based DSLAMs through a graphical-user
interface (GUI). CDM provides the following areas of network management: fault,
configuration, performance, and security. CDM runs within the Cisco Element Manager
Framework (EMF); both are installed on Sun workstations.
